A method is used to manufacture a lower jaw of an end effector of a surgical instrument. The method includes providing a lower jaw that includes a U-shaped body portion. The U-shaped body portion includes a bottom wall interposed between first and second opposing side walls. The method also includes forming at least one feature into at least one of the first and second side walls, wherein the at least one feature has a near net shape. The method also includes subsequently machining the at least one feature to have a machined shape.

A blender blade formed of titanium or titanium alloy is described herein. The blender blade comprises a central portion and one or more blade wings extending therefrom. Each blade wing comprises a leading edge, wherein the leading edge is work hardened to cause the leading edge to have a first hardness which is harder than a second hardness of the central portion. The central portion is in an annealed condition. The first hardness is in a range of about 40-50 HRC, the second hardness is in a range of about 20-30 HRC. Subsequent to work hardening, the leading edge can undergo nitriding and/or layer deposition.

A yard tool blade is provided with a distal edge to dig a work material, with a surface to support the work material and an adaptor at a proximal end for receipt of a handle. The distal edge is sharpened to an angle within a tolerance of forty to fifty degrees for a reduced thickness to cut the work material. A method for manufacturing the yard tool blade forms a yard tool blade blank. A cutting edge is machined on a distal edge of the yard tool blade blank. The yard tool blade blank is formed into a shaped yard tool blade. The shaped yard tool blade is heat treated after the cutting edge is machined on the distal edge.
